[...] la radiotoxicité spécifique d'un radionucléide n'est qu'un des facteurs de sa nuisance potentielle. Les quantités produites et leur évolution dans le temps, pour les nucléides de longue période leur accumulation, les phénomènes de concentration et de transfert, la combinaison de ces facteurs, peuvent dans certains cas justifier l'attention accordée à des radionucléides de faible radiotoxicité spécifique. Aussi a-t-on cherché à étudier tout particulièrement les radionucléides les plus importants par leur activité massique, leur durée de vie, les quantités produites ou les voies d'atteintes possibles, autrement dit par la nuisance potentielle qu'ils représentent. 5, record 1, French, - vie%20moyenne
